激活JTAG指令需要通过TMS信号运转状态机,依次进入Select-IR、Shift-IR和Run-Test/idle等状态,完成指令的加载和执行。 3.2 常用指令详解 EXTEST:该指令用于测试PCB上芯片之间的互连。测试序列包括输入EXTEST指令,通过TDI输入数据到芯片一,更新芯片一的输出管脚,芯片二捕获输入管脚数据,通过TDO输出数据。 BYPASS:该指令用...

到这里已经哪里都看不到错误了,领导问了句复位(他说的DSP复位,领导不用干活,经常鼓励下属就行)是不是好的,我说JTAG复位(我说的DSP_JTAG_TRST)确实没关注,一测,发现JTAG复位电平1.8V端高只有1V,低只有0.5V。 开始怀疑TXS0108芯片坏了,还换了一块好的芯片,仍然异常,去掉仿真器,强制TRST拉高,输出仍然异常,后...

三、Test data registers 参考JTAG标准第九章测试数据寄存器(Test data registers)、第10章旁路寄存器(Bypass register)、第11章边界扫描寄存器(boundary-scan register)。 此标准所定义的测试逻辑架构中,测试数据寄存器至少要包括两种寄存器,分别为旁路寄存器(Bypass Register)和边界扫描寄存器(boundary-scan register),当然...
The goal of this test is not only to check the IDCODE, but to communicate with theboudary scan register to read/write external I/O (not chek internal functions of the SOC).Checking the ID code validates the jtag chain (the right component in the right place) and after the testor go ...

这个intest指令,就是用来测试jtag接口的连接情况,看看它通不通,好不好使。 再来说说陕西方言。jtag的intest指令,就像咱们陕西的羊肉泡馍一样,得一步一步来,不能急。你得先把馍掰碎,再浇上羊肉汤,这样才能吃出味道来。同样,使用intest指令的时候,也得按照步骤来,先测试这个,再测试那个,才能确保jtag接口没问题...

Hi Team, I am using humming board pulse Solidrun linux board. I have connected JTAG segger link from my linux PC to the JTAG pins on my board. May i know how to test JTAG on my linux board. Thanks, Kartheek0 Kudos Reply All forum topics Previous Topic Next Topic 1 Reply 03-04...
